Chapter 3, Problem 3.70(choose chapter or problem)
The metal niobium (Nb) has a BCC crystal structure. If the angle of diffraction for the (211) set of planes occurs at 75.99 (first-order reflection) when monochromatic x-radiation having a wavelength of 0.1659 nm is used, compute thefollowing: (a) The interplanar spacing for this set of planes (b) The atomic radius for the Nb atom
